Simplified anti-vibration suspension for helicopter rotor

摘要

The anti-vibration suspension comprises three inclined bars (8) each articulated (9,11) on the structure (1) and the on the transmission box (2) by a rigid lever (12). The lever which supports a swinging mass (13) is pivoted on the transmission box. For each inclined bar a traction bar (16) is also articulated (17,18) on the structure and the transmission box. The corresponding lever is articulated on the box by pivoting on the upper end part of the corresponding traction bar.
